Safe and reliable electric 6 ton large electric hot water boiler performance is controlled and automated electric boiler power as an energy source in its class, its performance is now safe, reliable, controllable and automated boiler products. In addition to strict control, electric boilers need to operate in order to avoid personal risk. If the rice cooker for a long time, there will be aging. How to maintain electric boiler? Let's look at the maintenance of electric boilers: General Electric boilers must 1--2 years for repair and maintenance of electric boiler, is conducive to the normal operation of electric boilers. Electric boilers for regular maintenance is also essential to ensure its proper operation. Boiler maintenance, it must cut off the power supply and release the pressure. Burner every two months to be removed from the boiler body in order to remove foreign materials such as dust and carbon deposits. Photocell wipe once a month, fuel filter should always be clean and filtered. Carefully clean the filter in the pump, not to damage the gasket. Fuel oil is not the case in the absence of idling, so as not to damage the pump. Water level should always be kept clean, clean the valve should be opened once a day to ensure water clarity. Pull safety valve once a day, to prevent rust. After the work is completed, inspection tools, materials and accessories are complete, to prevent them left in the furnace space and so on. After delisting special person, you can complete the inspection before leaving the job site, ready for future maintenance records for the query.
According to instructions, "Neijiang City in 2017 and phase out coal-fired 6 ton large electric hot water boiler desulphurization facilities construction program of work", before the end of this year, the city built-up area will be fully phased out in Neijiang City, 10 steam tons / hour of coal-fired boilers and a total of 46 units. Among them, a small city in district out of coal-fired boilers 26, and phase out coal-fired small boilers Dongxing District 15, Neijiang Economic Development Zone small coal-fired boilers out of five. At the same time, accomplish four Chuansha Qi Industrial Co., Ltd. Two 20 tons of steam / hour or more coal-fired boiler desulphurization facilities. A ban on new urban area 20 steam tons / hour of coal-fired boilers, other counties (cities, districts) in principle, the new 10 steam tons / hour of coal-fired boilers. Out of the way including demolition scrap, coal to gas, coal and electricity upgrade boiler swap with large capacity.
We understand that the new Neijiang 20 tons of steam / hour for coal-fired boilers built-up areas, the new 10 steam tons / hour or less fixed asset investment projects in other areas of development and reform, economic and information technology departments will not be approved, approval and filing, environmental protection departments at all levels shall not pass environmental impact assessment, quality supervision departments at all levels do not accept the installation told not arrange supervision and inspection, no special equipment issued registration certificate. Quality supervision departments at all levels cancellation of special equipment for the boiler has been out of use registration certificate to prohibit the production of boiler manufacturers boiler does not meet industrial policy.
1 ton and 1 ton electric gas-fired 6 ton large electric hot water boiler, whose lower operating costs?
"How much gas consumption", "is saving" has been one of the problems users are most concerned about the purchase of a boiler. The onset of winter, provide a large area for hotels, hospitals, shopping malls, entertainment and other heating and domestic hot water boiler equipment also received much attention. Today, Zhengzhou party fast small series to introduce some simple operating costs on gas boilers and electric boilers contrast problems.
The inlet speed of gas-fired hot-water 6 ton large electric hot water boiler before start-up should not be too fast, usually no less than 4 hours in winter, and 2-3 hours in other seasons, especially in the initial stage of water intake. The inlet temperature of a gas-fired hot water boiler is generally 50 °C, so the difference between the feed water temperature and the steam wall temperature in the drum is less than 40 °C. For gas-fired hot water boiler, the inlet water temperature can be equal to that of steam drum wall without complete cooling, otherwise the inlet water speed should be slowed down. When feed water enters the drum, it always first touches the lower part of the drum. If the difference between the feed water temperature and the drum wall temperature is too Large, the inlet speed is fast, and the upper and lower walls of the drum, the inner and outer walls will have a large expansion. Bad, on the drum caused a lot of additional stress, resulting in drum deformation, serious cracking. Due to the thickness and slow expansion of the drum wall, the tube wall connected to the drum wall is thinner and expands faster. If the inlet temperature of the gas-fired hot water boiler is too high or the inlet speed is too fast, the expansion will be uneven, the welded joint will appear cracks and the gas-fired hot water boiler will be damaged. The inner diameter of the decompression tube is usually φ 7~13mm (water and steam), and its length should not be too long (< 60m). Straightness of pressure pipe If the diameter is too small and the length is too long, it will affect the dynamic transmission of pressure measurement and increase the dynamic error. The inner diameter is too large to be easily maintained and installed. Pressure pipes should not be placed in the horizontal part to prevent the accumulation of bubbles (when measuring liquids) and water columns (when measuring gases). The pressure tap shall be perpendicular to the flow of the medium. Pressure faucet must not have chamfer, flange and burr. When measuring the hydraulic pressure of an electrically heated steam boiler, the pressure outlet should be removed from the lower part of the pipe to prevent the gas in the liquid from entering the pressure guide pipe; When measuring the gas pressure, remove the pressure splice from the upper part of the pipe to prevent dust and dust in the gas The droplets enter the ignition line. The installation site of the electric heating steam boiler pressure gauge (pressure transmitter) should meet the environmental conditions (temperature, humidity, vibration, etc.) used by the instrument, and should be easy to observe, repair and ensure safety. Insulation should be laid on pressure pipes in high temperature media to avoid burning during flushing. Pressure lines are equipped with needle valves (for cutting off pressure in the event of pressure line failures during operation), auxiliary needle valves (for use with instruments, stopping, replacement), condensing coils and elbows (isolation elastic elements from high-temperature media), Easy to install sealing gaskets) as well as sewage valves and sewers. For special pressure measurements, it's still pressing. Install discharge valve, isolation room and so on in the force pipe.
Commercial electric hot water boilers? Commercial electric hot water boilers are available form 50kW all the way up to 1 Megawatt output. At these kW outputs the boilers are powered by a 3 Phase / 400 Volt electrical supply and can be used to not only do the wet heating system, but also to do domestic hot water via a calorifier or cylinder.Get a Quote
